[0021] The following further describes the present utility model with reference to the drawings and specific embodiments.

[0022] As Figures 1-5 shown, a coke moisture test device includes a sample tray 1, a lifting mechanism, an oven 3, a flattening mechanism and an electronic balance 5,

[0023] A horizontal moving mechanism is installed on the lifting mechanism; a sample tray fork 24 is fixed on the horizontal moving mechanism, and the sample tray fork 24 is lifted and moved vertically and horizontally through the lifting mechanism 2 and the horizontal moving mechanism; a supporting part 11 matching with the sample tray fork 24 is fixed at the bottom of the sample tray 1. After the sample tray fork 24 extends into the supporting part 11, the sample tray fork 24 is raised to lift the sample tray 1. The supporting part 11 can be composed of two vertical support plates, and the sample tray fork 24 can extend between the two support plates to lift the sample tray 1.

[0024] The oven 3 is arranged on one side of the lifting mechanism; the flattening mechanism is arranged between the lifting mechanism and the oven 3, and the coke on the sample is flattened through the flattening mechanism; the electronic balance 5 is fixed on the oven 3.

[0025] The lifting mechanism includes a column 21, and a lead screw guide rail is vertically installed on one side of the column 21; a slider is installed on the lead screw guide rail; the horizontal moving mechanism is installed on the slider; a lifting motor 23 is installed above the lead screw guide rail. By driving the lead screw of the lead screw guide rail to rotate through the lifting motor 23, the slider is lifted and moved.

[0026] The horizontal moving mechanism includes a cylinder 22, and the cylinder 22 is fixed to the slider; the sample tray fork 24 is fixed to the piston rod of the cylinder 22; the piston rod of the cylinder 22 faces the oven 3.

[0027] The flattening mechanism includes a vibrating plate 41; four vibrating springs 42 are arranged around the bottom of the vibrating plate 41; a vibrating motor 43 is fixed to the bottom of the vibrating plate 41. When the sample tray 1 is placed on the vibrating plate 41, the vibrating plate 41 is vibrated through the vibrating motor 43, so as to flatten the coke on the sample.

[0028] In this embodiment, a turnover and waste discharging mechanism is further included. The turnover and waste discharging mechanism is arranged on the side of the flattening mechanism away from the horizontal moving mechanism, that is, on the side of the vibrating plate 41 away from the column 21. The turnover and waste discharging mechanism includes a support base 51, a turnover motor 53 and a turnover seat 52. A slot is formed in the support base 51. A part of the turnover seat 52 is inserted into the slot, and the other part is above the support base 51. The turnover motor 53 is arranged on one side of the support base 51, and the output shaft of the turnover motor 53 is inserted into the support base 51 and connected to the turnover seat 52. The turnover seat 52 can be rotated by 90° through the turnover motor 53. Two opposite clamping plates 54 are arranged on the turnover seat 52. The clamping plates 54 are in an "L" shape. The two clamping plates 54 can move relatively to clamp the sample tray 1. The lifting mechanism and the horizontal moving mechanism place the sample tray 1 after the test between the two clamping plates 54 on the support base 51. The sample tray 1 is clamped by the two clamping plates 54. Then the turnover motor 53 is started to rotate the turnover seat 52, the two clamping plates 54 and the sample tray 1 by 90°, and the materials on the sample tray 1 are discharged. After the discharging is completed, it is turned back to the original position.

A clamping motor is fixed in the turnover seat 52. The output shaft of the clamping motor is connected to the gear 521. By starting the clamping motor, the gear 521 rotates, so that the two racks 522 move relatively, and further the two clamping plates 54 move relatively.

[0030] Usage method of the utility model: During moisture testing, the coke automatic sampling system sends a signal to the moisture testing system, and the lifting mechanism and the horizontal moving mechanism are automatically started. The door of the oven 3 is opened, and the sampling tray 1 is taken out from it and moved to the electronic balance 5. The chute above the electronic balance 5 discharges materials, and the materials fall into the sample tray 1. After receiving the materials, the lifting mechanism and the horizontal moving mechanism take the sample and transport it to the lower vibration area to level the coke. Subsequently, the materials are transported to the electronic balance 5 for sample weighing. The lifting mechanism and the horizontal moving mechanism transport the weighed sample into the oven 3 for baking with the door closed, and the lifting mechanism returns to the origin position. When the baking time is up, the door of the oven 3 automatically opens, the lifting mechanism and the horizontal moving mechanism take the sample and move it to the electronic balance 5 for weighing again. The electronic balance 5 uploads the weights of the two weighings to the moisture testing system, and the moisture content of the coke is obtained based on the two weighings. Then, the lifting mechanism and the horizontal moving mechanism move the sample tray 1 to the flipping and discharging mechanism 5. The sample tray 1 is clamped by two clamping plates 54, and then the flipping motor 53 is started to rotate the flipping seat 52, the two clamping plates 54 and the sample tray 1 by 90°, discharging the materials on the sample tray 1. After the discharging is completed, it flips back to the original position. The lifting mechanism and the horizontal moving mechanism transport the empty sample tray 1 back into the oven 3, the oven 3 closes the door, and the lifting mechanism returns to the origin.
